2000 Chevrolet Blazer LS 4.3L Poor Idle Quality, Misfire, MIL Lamp on
This vehicle has a P0300 code, I have replaced the Spider assembly, Ignition wires, cap and rotor, spark plug and miss fire returns. Fuel pressure and all systems seem normal. Idles very rough and smooths out a little when accelerated.
